CASH-REGISTER.

SPECIFICATION forming part; of Letters Patent No, 312,740, datedFebruary 24, 1885. Application filed July 7, 1884. (No model.)

I 0 all whom it may concern:

Be it known that I, WILLIAM C. McGrLL, a citizen of the United States,residing at \Vashington, in the District of Columbia, have inventedcertain new and useful Improvements in Gash-Registers, of which thefollowing is a specification, reference being had therein to theaccompanying drawings, and in which- Figure 1 is a perspective view ofmy improved cash-register. Fig. 2 is a verticalsection of the same. Fig.3 is a perspective view of one of the registeringcylinders and its operating slides and dials, showing portions of the casing broken away.Fig. 4 isarear view of the same. Fig. 5 is a perspective detail View ofone of the operating-slides and a portion of the casing. Fig. 6 is avertical sectional detail view of one of the slides, a portion of thecasing, and the mechanism locking the lid of the cash-box; and Fig. 7 isa perspective detail view of one of the slides and its notchedspring-pawl.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to that class of cash-registers in which aslide operating the register and corresponding to the amount paid ispushed down at every sale; and it consists in theimproved constructionand combination of parts of an apparatus in which the actuatlug-slidesare provided with spring-pawls having a number of notches correspondingto the number of the amount,and slide tangential to aregistering-cylinder having a number of transverse rounds,and in whichthe actuatingslides operate a plate locking the cash drawer or box aftereach sale, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the casing of theapparatus, thelower end of which casing is provided with aforwardly-projecting extension, B, which forms the cash-box, and whichis provided with a lid, 0, hinged at its forward edge to the upper edgeof the forward side of the box, and provided at its inner free edge witha metallic strip, D, which rests upon the sill E, formed by the upperedge of the rear side piece of the cash-box. The under side of the lidbears against the forward end of a lever, F, pivoted in the rear sidepiece of the cash-box, and the rear end of this lever bears against theunder side of the end of a lorwardly-curved or doubled spring, G,secured in the botttom of the casing, and the forward end of this springhas a hammer, H, attached to it, which hammer may when it is forced downstrike a bell or gong, I, secured upon the side of the casing, the leverhaving its forward end depressed when the lid to the cash-box is closed,which will raise the rear end of the lever, and raise the end of thespring and the hammer, and when the lid ofthe box is opened the leverwill be permitted to rock freely, releasing the end of the spring andthe hammer, allowing them to spring downward, when they will sound thegong, giving alarm that the drawer or box is opened.TheslidesJslideinslotsKinthefront plate,L, of the casing, and areprovided at their upper ends with outwardly-projecting handles orlips M,upon which the number corresponding to the slide is preferably marked,and the same number is preferably marked upon the bottom of the slot inwhich the slide travels, so that the number will be visible when theslide is moved down. Spring arms or pawls N are secured at their lowerends to the lower ends of the slides, and are of the same length as thedistance which the slides may move,and the said spring arms or pawlshave upon their inner edges a number of beveled or inclinedratchet-teeth, 0, corresponding in number to the number upon the slide.These slides and arms slide tangentially to one or more cylinders, P,consisting of two heads, Q Q, and a number of rounds, It, and journaledin the casing to the rear of its front plate, and the rounds in thesecylinders correspond in distance to the teeth upon the spring arms orpawls, so that when one slide is pushed down its springarm will revolvethe cylinder as many rounds forward as there are teeth upon the arm. Apawl, S, secured to the casing, engages the rounds of the cylinder andprevents the same from being reversed, and one end of the shaft T of thecylinder is provided with an index,U,which points upon the figures of adial, V, concentric with the shaft; and the head of the cylinder has aprojecting lug, XV, which will once in each revolution engage with atooth of a cog-wheel, X, which is prevented by a pawl, Y, from beingreversed,

and the shaft of this cog-wheel has an index, Z, which points uponthe-nuinl'iers of a dial, A, concentric with the shaft of the wheel. Thegraduations of the dial for the index of the cylinder are graduated tocorrespond to the number of rounds in the cylinder, and the two dialswill register how many rounds the cylinder has been revolved, andconsequently how many units of the denomination of coin registered bythis cylinder, there being preferably one cylinder, and consequently oneset ofslides from 0 to 9 for each denoniination of coin to beregistered, the drawings, for instance, showing the register adapted forthe United States money, there being a cylinder and register fordollars, dimes, and cents. \Vhere a number of cylinders and registersare used, as in the register shown in the drawings, the casing isdivided by a number of partitions, B, in which the ends of the shaftsare journaled, and to which the dials are secured, as well as the pawls,preventing the cylinders and cog-wheels from being reversed. The lowerportion of the front plate of the casing is bulged slightly forward, asshown at O, and a strip or plate, D, is secured to a spring, E, securedto the inner side of the front plate, and extends the entire length ofthe row of slides, and has its lower edge, G,

bent outward, adapted to be projected out through a slot, H, formedbetween the lower edge of the front plate of the casing and the upperedge or sill of the cash-box. The spring serves to force the lowerportion of this strip or plate inward, and when a slide is pushed downthe lower end of the said slide will force the lower edge of the plateoutward, which will cause the said outwardlybent edge to catch over thestrip upon the edge of the lid, and thus lock thelid until the slide israised, when the lid may be opened, the cash deposited, and, ifnecessary, change given, when the lid is again closed and the slide orslides indicating the amount of the last sale pushed down, locking thelid again, while the slides which are down will indicate the amount ofthe last sale, andv must not be changed until a new sale is to beregistered.

It will be seen that the dials will indicate the exact amount of moneythat ought to be in the cash-box, and that it is'impossible to get intothe eash-box without releasing the slide or slides down at that time,and without sounding the alarm, and that for the purpose of locking thelid again an amount must nee I essarily be registered, the apparatusthus effectively preventing tampering with the cashbox and registeringexactly every return made to the box.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States 1. In a cash-register, a drawer, aregisterdial, a cylinder having a number of equidistant rounds, its axisbeing provided with an index, a series of plates having ratchet-bars,and provided with numbers corresponding to the numbers on the index ofthe cylinder, and a movable bar or plate arranged to be operated by anyone of said series of plates for the purpose of locking the drawer, all.in combination, substantially as set forth. 2. The combination of thelid of the cashbox, provided with the strip at its free edge, thelocking-plate having its lower end bent outward, adapted to engage thestrip of the lid, the spring forcing the lower edge of the looting-plateinward, and the slides bearing with their lower ends against the back ofthe locking-plate, as and for the purpose shown and set forth.

the casing having slots in its front plate, and having the said frontplate formed with a bulge at its lower edge and with a slot between thelower edge and the sill of the caslrbox of the casing,'the hinged coverof the cash-box having the strip upon its free edge,adapted to rest uponthe sill of the box, the lever pivoted in the rear side of the box, thedouble-curved spring secured to the bottom of the casing, bearing withits forward end against the rear end of the lever, and provided with thehammer at the said end, the bell or gong, theloeking-plate having itsloweredge bent outward, projecting through the slot of the front plate,and secured in the bulge of the front plate, forced inward at itslowerend byits securingsprings, and the cash-registering slides bearingwith their lower ends against the rear side of the locking-plate,adapted to force itslower edge outward when pushed down, as and for thepurpose shown and set forth.

In testimony whereof I affix my signature in presence of two witnesses.
